Effect of the alkyl linker length on the photoisomerization of hydrazone switches on metal surfaces [PDF]
, 2022 A series of bistable hydrazone switches containing alkyl thiolate linkers of various lengths (Cn HAT, n = 3, 8, 10, and 11) were synthesized. We explore the length effect of the carbon chain on the photoisomerization of hydrazone switches using UV-vis ...

Catalysis of Hydrazone and Oxime Peptide Ligation by Arginine [PDF]
, 2020 Hydrazone and oxime peptide ligations are catalyzed by arginine. The catalysis is assisted intramolecularly by the side-chain guanidinium group. Hydrazone ligation in the presence of arginine proceeds efficiently in phosphate buffer at neutral pH but is ...
